Overview
2004 Grady-White 300 Marlin
This 2004 Grady-White 300 Marlin represents an exceptional opportunity to own one of Grady-White’s most respected offshore models, thoughtfully updated and maintained to a standard that is increasingly difficult to find in boats of this vintage.
Repowered in 2018 with twin Suzuki DF250 four-strokes, currently showing approximately 850 hours, this 300 Marlin benefits from a long list of meaningful upgrades spanning propulsion, electronics, fishing equipment, cosmetics, and mechanical systems.
At the helm, the electronics package has been substantially modernized and includes a 2018 Garmin 12" GPSMAP, and a 2022 Garmin 16" XSV display, Garmin 18" HD radar, 2022 Simrad autopilot, Sirius satellite radio, and a 2024 FLIR thermal camera. New Llebroc helm chairs were installed in 2023, while a new enclosure completed in 2022 keeps the helm well protected and comfortable throughout an extended boating season.
The fishing equipment is equally impressive. In 2025, the boat received 18' carbon-fiber Gemlux outriggers, along with new fresh- and saltwater washdown pumps. New fuel lines and fuel-filter housings were also installed in 2025.
Below the waterline, the bottom was completely stripped and barrier coated in 2023, addressing one of the most important long-term maintenance items on a boat of this age.

The 300 Marlin has earned its reputation through a combination of Grady-White’s proven SeaV² hull, serious offshore capability, a highly functional fishing cockpit, and a cabin that makes overnight trips and extended days on the water genuinely comfortable.
With its newer Suzuki power, extensively upgraded electronics, premium fishing equipment, and years of thoughtful improvements, this particular 300 Marlin stands well above the typical example of its vintage.
For the buyer searching for a proven offshore platform without the cost of outfitting and updating an older boat from scratch, this is a rare opportunity to acquire a truly turn-key example of a legendary Grady-White fishing machine.
